On real roads it will struggle to come close to these numbers. These 2 wheel drive cars are all traction-limited at low speeds. And if it wasn't for those huge tyres and hi-tech rubber, they would never do sub 3 second 0-100 kph on roads.

Mindboggling. Imagine it does 170 in the time it took the Bentley to do 130 and in less time than it took the Performante to do 150 mph. Even more incredible is it's gentle ride and forgiving nature. Needed better tyres though. The third fastest in a straightline-the GT R was the Iron King of the track. It's a little twitchier and harsher but is a lot cheaper. And the 720s was tezted at 667 m or 2200 feet above sea level!

I doubt the Huayra BC can do a 2.3 second 0-62mph time. The LaFerrari has a power to weight of 1.65kg/cv, but Ferrari claimed 2.9 seconds. Also, the quickest the LaFerrari has done it in is 2.5 seconds, and it has a dual clutch.

Go on custom race and put the hardest difficulty and race against N700 cars. Performance in quick race isn’t accurate, I was quicker than a LaFerrari with the 650S. But on custom race, I couldn’t hang with the Veneno, Veyron 16.4 or LaFerrari.

It said 698whp is 823hp, don’t know if it means just hp (metric (cv/ps)) or bhp.

823hp = 811bhp / 834hp = 823bhp

If it has 834hp while weighing 1419kg, power to weight ratio is 1.7kg/cv. However, if it has 823hp, power to weight ratio is 1.72kg/cv.

To compare to the Holy Trinity, the 918 Spyder Weissach Package is 1.84kg/cv (887hp, 1634kg), the LaFerrari is 1.64kg/cv (963hp, 1585kg), and the P1 is 1.62kg/cv (917hp, 1490kg).

So the 720S has a better power to weight ratio than the 918 Spyder Weissach Package, but not the P1 and LaFerrari. I’d assume in a roll race, P1 and LaFerrari win because they also have more torque, unless McLaren also underrated torque figures of the 720S.

The P1 and LaFerrari also have better torque to weight. But because the McLaren launch control is awesome and gets better and better, the 720S is quickest off the line. Least torque and horsepower, so least wheelspin.
